So if I spend $80 to give someone a tech, then they can pay off the debt either by sending me another $80 tech, or by giving me $80 cash, right? But the cash option doesn’t seem fair - the other player got the tech while I got no net benefit from the deal!
It’s for alliances. Makes it easy to share tech and get paid back instantly for transfer fee. If you don’t want to pay then don’t do it.
I would suggest making a single thread with all of these ideas and bugs, instead of a new thread every time something new pops up. A thread should promote discussion, as opposed to just a spelling error that nobody but Jay needs to see.
